Generation and manipulation of multipole and vortex events in (1+1)-dimensional spacetime
Yiming Pan, Guowei Chen
An event is usually regarded as a zero-dimensional coordinate label in spacetime, rather than as an object with spatial extent, internal structure or topology. Here we show that in…
Time domain Stokes mechanism of pair correlated k gap solitons in nonlinear photonic time crystal slabs
Jiaxiang Sun, Guowei Chen, Liang Zhang +1
Pair generation in time-varying media is commonly attributed to time reflection at temporal boundaries or to amplification inside momentum k gaps. Here we show that these two proce…
Breathing k-Gap Events and Instability on Instability in Nonlinear Photonic Time Crystals
Liang Zhang, Chenhao Pan, Yiming Pan
Photonic time crystals (PTCs) host momentum bandgaps, or k gaps, that enable parametric amplification and lasing of seeded fields. In nonlinear PTCs, Kerr saturation dynamically su…
Quantization and Biphoton Statistics of k-Gap Solitons in Nonlinear Photonic Time Crystals
Liang Zhang, Chenhao Pan, Yiming Pan
Nonlinear photonic time crystals (PTCs) can support solitons inside momentum k gaps, where the amplification of k gap modes is saturated by Kerr nonlinearity, forming spatially hom…
Data-driven reconstruction of band dispersion and quantum geometry via Koopman dynamical mode decomposition
Yiming Pan, Jinze He, Jiapeng Yang +1
We present a data-driven framework for reconstructing band structures using Koopman operator analysis and dynamic mode decomposition (Koopman-DMD). Instead of deriving spectra from…
Topologically-protected superluminal pair annihilation in photonic time crystals
Liang Zhang, Chenhao Pan, Jinze He +4
Photonic time crystals (PTCs) - dielectric media whose permittivity is periodically modulated in time - map to a Dirac equation with an imaginary mass, opening a momentum gap (k-ga…
Amplifying solid-state high harmonic generations with momentum k-gaps in band structure engineering
Yiming Pan, Danni Chen, Xiaoxi Xu +2
We propose a novel amplification mechanism for high harmonic generation (HHG) in solids by leveraging bandgap engineering with momentum k-gaps. By constructing a simple diatomic la…
Event Soliton Formation in Mixed Energy-Momentum Gaps of Nonlinear Spacetime Crystals
Liang Zhang, Zhiwei Fan, Yiming Pan
We report the formation of a novel soliton, termed event soliton, in nonlinear photonic spacetime crystals (STCs). In these media, simultaneous spatiotemporal periodic modulation o…
Symmetry Breaking and Spatiotemporal Pattern Formation in Photonic Time Crystals
Egor I. Kiselev, Yiming Pan
In this work, we explore the dynamics of time varying photonic media with an optical Kerr nonlinearity and an associated phase transition. The interplay between a periodically modu…
Light controlled THz plasmonic time varying media: momentum gaps, entangled plasmon pairs, and pulse induced time reversal
Egor I. Kiselev, Yiming Pan, Netanel H. Lindner
This letter establishes a Floquet engineering framework in which coherent high frequency light with a time dependent amplitude can be used to parametrically excite and amplify THz…
